I haven't been following this thread very closely, so forgive me if I'm 
off base.

Almost every application I've seen that supported multiple backends had 
one backend that worked properly and was used by everybody and all 
others were either unimplemented or poorly maintained and 
flaky/unusable. Effectively, they had only one backend.

So unless you've definitely identified a use-case for multiple backends, 
toss the feature. The plugin infrastructure simply adds complexity for 
minimal benefit. You'd be better served by a modular design that allows 
for an easy rewrite of the backend if needed.
